Thanks for your help. I solved my problem by flashing my board with the default firmware in T2Laser. Now it works perfect!
@Zax well, i reinstalled the software but i still have this problem. nothing changed. How can i changed the steps in the software? i didn´t even found a way to open the software setup in arduino to change parameters.
My 2 y-axis should move for example 10mm, but they actually move more than 30mm, why. And how can i fix this?
